Abstract: Structure design is the selection of materials and member type ,size,
and configuration to carry loads in a safe and serviceable fashion .In
general ,structural design implies the engineering of stationary objects such as
buildings and bridges ,or objects that maybe mobile but have a rigid shape such as
ship hulls and aircraft frames. Devices with parts planned to move with relation to
each other(linkages) are generally assigned to the area of mechanical .
Key words: Structure Design ； Structural analysis ；structural scheme ；
Project requirements
Structure Design
Structural design involved at least five distinct phases of work: project
requirements, materials, structural scheme, analysis, and design. For unusual
structures or materials a six phase, testing, should be included. These phases do not
proceed in a rigid progression , since different materials can be most effective in
different schemes , testing can result in change to a design , and a final design is often
reached by starting with a rough estimated design , then looping through several
cycles of analysis and redesign . Often, several alternative designs will prove quite
close in cost, strength, and serviceability. The structural engineer, owner, or end user
would then make a selection based on other considerations.
Project requirements. Before starting design, the structural engineer must
determine the criteria for acceptable performance. The loads or forces to be resisted
must be provided. For specialized structures, this may be given directly, as when
supporting a known piece of machinery, or a crane of known capacity. For
conventional buildings, buildings codes adopted on a municipal, county , or , state
level provide minimum design requirements for live loads (occupants and
furnishings , snow on roofs , and so on ). The engineer will calculate dead loads
(structural and known, permanent installations ) during the design process.
For the structural to be serviceable or useful , deflections must also be kept
within limits ,since it is possible for safe structural to be uncomfortable “bounce”
Very tight deflection limits are set on supports for machinery , since beam sag can
cause drive shafts to bend , bearing to burn out , parts to misalign , and overhead
cranes to stall . Limitations of sag less than span /1000 ( 1/1000 of the beam length )
are not uncommon . In conventional buildings, beams supporting ceilings often have
sag limits of span /360 to avoid plaster cracking, or span /240 to avoid occupant
